System features

• For connection options → Overview figures of the control concepts.
• The sensor limit values for Object or RC units are stored permanently and cannot be changed. Sensor limit values for comfort units can be changed/set with the commissioning software.
• The operating mode set on a RLS 45 O or RLS 45 K and the ventilation level apply to all room air controls and ventilation units, as does the External OFF function.
• Additional functions (intermittent ventilation, sleep mode) only apply to the ventilation units on the relevant room air control.;
• The supply air function is only performed by the ventilation units connected to the respective room air control.
• Service mode: Mode intended for the specialist installer to make settings and setup the unit functions and to register wired sensors.
• Commissioning software (RLS 45 K): The commissioning software can also be used with the RLS 45 K control.
• If you have an odd number of units (3 or 5 ventilation units), the control ensures compensation of volumetric flow compensation between the supply air and exhaust air units → Service mode. In case of an uneven number of ventilation units, the smaller number of devices is connected to the fan 1 terminals.
• Stand-alone units can be operated with an additional exterior wall air opening (in the same room).
• The ventilation system should be switched on permanently.
• The function Demand-driven automatic operation is only available if a sensor is connected and activated in service mode.
